A circuit arrangement of this embodiment of FIG The invention is described below with reference to FIGS. 3A and 3B which are mutually connected as in FIG Fig. 2 are linked. The circuit arrangement of FIGS. 3A and 3B has five blocks and Circuits for linking these blocks. The blocks and the circuits are made up of circuit * - areas of large group integration (LSI) or made from hybrid IC. In particular, this means Reference numeral 10 is a key input section which is entered by the associated keys on the keypad 1 is operated; 20 a musical tone generating section including a circuit for forming a Musical tones, an input operation control circuit, and the like; 130 a memory section including first and second memories 131 and 132 and their peripheral circuitry; 140 a control section for controlling read and write actions for the memory section 130 and 50 an amplifier. The first memories 131 and 131 are semiconductor memories made of, for example, RAMs (Random access memory). The operation of these blocks 10 through 50 and their associated circuitry is explained below.

The tone generation section 20 mentioned above has a 4-bit note counter 21 and a 2-bit block counter 22 for scanning the keypad 1 and to recognize one or more pressed keys. A clock signal φΑ for sampling is in the first stage of the note counter 21 is provided. The note counter 21 transmits its content to a note decoder 23. The note decoder 23 generates monoflop signals via 12 lines 23a to 23 at different times 231, which correspond to twelve pitches "C to B" corresponding to the numbers "0 to 11" of the note counter 21. The note decoder probes with the generated monoflop signals 23 the same pitches or tones in the

1300 rev / 1368

corresponding octaves of the input section IO. An output signal appears on a line 23m of the note decoder 23 when the content of the note counter 21 reaches the number "12". The output signal on the line 23m is applied as a reset signal to the note counter 21 and as a counting clock to the block counter 22. The block counter 22 counts on the count clock out wherein an output signal is generated. Accordingly, the number ¹¹ O turn is applied to a block decoder 24 to 3 "of the block counter 22 of the block decoder 24 generates different time setting signals via lines 24a to 24d. After flowing through the line 24a to 24d, these signals are applied as octave detection signals to the AND logic 25a to 25d. The output signals from the AND logic 25a to 25d are applied via an OR logic 26 to a shift register 27 which has a capacity of 48 bits, which corresponds to the number of keys in the key input section 10, and has the function of a series-parallel converter. The shift register 27 has bit positions corresponding to the keys in the key input section 10 for storing the data of the pressed keys. The parallel output signals from the shift register 27 are applied to a buffer 28 which has the same capacity, ie 48 bits, as the shift register 27. When all the keys in the key input section 10 are scanned, the output signals from the shift register 27 are input to the buffer 28. For this purpose, the buffer 28 has a read signal as an output signal from an AND logic 28a, which is connected at the input to the output signals which are applied via a line 23m of the note decoder 23 and a line 24d of the block decoder 24. The output from the buffer 28 is transmitted to a tone generating circuit 29 for generating various tone signals. The tone generating circuit 29 digitally forms different tone signals in accordance with the pitches

1 300U / 1368

the buttons. The musical tone signals digitally generated by the circuit 29 are sent to a digital / analog converter chaitkreis 29a created, where they are converted into corresponding analog signals, which in turn by an amplifier 50 are amplified and then make a loudspeaker 4 sound. The edition from switch 3 to the musical tone generating circuit 29 applied, the predetermined musical tone signals generated in accordance with the output signals from the buffer 28 and the switch 3.

The arrangement of each crossing point of the lines in the row and column of the key input section 10, as shown in detail by the circle 11, consists of a combination of one Diode 12 and a switch 13, linked to each key on the keypad i. There are 48 switches of four octaves combined to form a matrix of four rows and twelve columns. The spa lines of the key input area 10 extend from the lines 23a to 231 of the note decoder Each column line is connected to keys that have the same tone name in different octaves while each row line is connected to the keys corresponding to the twelve pitches from "C to B" correspond. The key input section 10 generates signals indicating the key operations at timing represent the associated tone designations via the line 10a to 1Od.

The key operation signals passed through lines 10a to 10d are then sent to the AND logic 161a to 16id. The expenses from the AND logics 161 a to 161d are linked to the AND logics 25a to 25d applied. The key press signals from the lines 10a to 10d are also input to the memory section 130. In memory 130 the input signals are made by the AND logics

1300U / 1368

131 a to 131d to a first memory 131 and through the AND logics 132a to 132d to a second Memory 132 created. The first and second memories 131 and 132 are also assigned the note code.

c, which is transmitted via lines 23a to 231 will.

Those from the first and second memories 131 and 132 read out data are sent to the AND logics 131e

ig to 131h and applied to the AND logics 132e to 132h. The corresponding outputs of the logics 131e to 131h and 132e to 132h are with the AND logics 25a to 25d wired and connected to them. The AND logics 131 a to 131d, 132a to 1 32d, 131 e to 131h and 132e to 132h are by the control signals C, D, F or E are switch-controlled, which are output by a control unit or a control section 140. The control section 140 also generates read: / Write control signals c and d for the first and second memories 131 and 132 and signals H and G for incrementing the addresses of the associated memories 131 and 132 at the time of reading and Writing. In response to the output signals transmitted through lines 10a to 10d of the key input area arrive in connection with the switches 2a to 2d shown in Fig. 1 and the clock signal <j> a out the control section 140 generates control signals C to H for the memory section 130 and switching control signals A. and B for the AND logics I6ia and I6ib to I6id.

Details of the control area 140 are shown in FIG. Incidentally, it should be mentioned that the output and Input terminals of the circuit diagram shown in Figure 4 are not in their positions with the terminals of the circuit shown in Fig. 3C match.

The control section 140 has the counters 1401 and 1402 which in their structure correspond to the note counter 21 and the

1300U / 1368 BAD QRIGINAt

Block counter 22 are similar. The counting cycle ^ A is sent to the first stage of counter 1401 applied. A signal that detects that the content of counter 1401 is "12" is applied to the reset terminal of counter 1401. The reset signal that is on the counter 1401 is applied, is used as a counting clock signal applied to the counter 1402. The output of the counter 1402 is input to a decoder 1403, which is similar in structure to the block decoder 24.

The key press signals arriving through lines 14a to 14d are through a key timing detection circuit 1404 is selected with respect to the output signal from the decoder 1403 and the selected signal is output by an OR logic 1405. Accordingly, the output signal from the OR logic 1405 the bit timing that matches the associated key. That of the or logic 1405 issued key actuation signal is applied to the AND logics 1406 and 1407, their outputs can be applied by the OR logic 1408 to a shift register 1409 with a 48-bit capacity. The end- gabesignai from the shift register 1409 is sent directly to the AND logic 1407 and through an inverter 1410 applied to the AND logic 1406. The AND logic 1406 generates an output signal when there is an additional Receives key actuation signal. The AND logic 1407 generates an output signal when it is the same key press signal receives.

The parallel outputs from the shift register become to latch circuit 1412 when AND logic 1411 designates that the content of counter 1401 is "12" and the content of the counter 1402 is "3", i.e. the scanning of all keys is completed. In connection with the issue of the latch circuit 1412 becomes the lower 12 bits, i.e. the output signals from the bit positions of the interlock circuit 1412 for

1300U / 1 368 BAD ORIGINAL

Storage of the key operation signal that on the Line 10a appears from the latch circuit 1412 through an OR logic 1413 and an AND logic 1414 is output in the form of the logic control signal F for the AND logics 131e to 131h. The remaining bit signals are output from the latch circuit 1412 through an OR logic 1415 and a AND logic 1416 in the form of the logic control signal Ξ for the AND logics 132e to 132h are output.

The AND logic 1406 generates a "1" signal when a another key is pressed. The output from AND logic 1406, along with the output signals (the control signals A and B) from the inverters 1417 and 1418, the inversions of the output signals from the Switches 2a and 2b are applied to an AND logic 1419. The output signal from AND logic 1406 and the output signal from an OR logic 1422 to detect that the content of the counter 1402 is "1 to 3" are applied to an AND logic 1420 along with the output signal from switch 2b. That Output signal from AND logic 1406, the output signal generated by OR logic 1422, when the counter 1402 generates a "0" signal, and that Output signals from the switch 2a are applied to an AND logic 1421. The output signals from the AND logics 1419 and 1420 are applied to an OR logic 1423, which in turn provides an output signal as an incremental signal G for the second memory 132 is generated.

The output signals from the AND logics 1419 and 1421 are by an OR logic 1424 to the first Memory 131 in the form of the incremental signal H applied.

The output signal from the switch 2c is used for the memory section 130 as a logic control signal for the AND logics 131a to 131d and as read / write signals is generated for the first memory 131 and is accordingly designated as C. The output signal from

1300H / 1368

the switch 2d is used as a control signal for the AND logics 232a to 232d and as a read / write signal is generated for the second memory 132 and is denoted as D.

The following explains the case where, with such an arrangement, an accompanying note set is preceded was stored and when playing a piece of music the first key group 1a as a reading function is used, while the second group of keys 1b is used for manual play. So it will a melody is played manually using the second group of keys Ib. Refer to Figure 5A and FIGS. 5B and 6A to 6F are referred to.

To store the set of accompanying notes, the key group 1a is used for the reading function and playback of this key group and the switch 2c is switched to on in order to switch the AND logics 131a to 1 31d into the working position, whereby the accompanying note set is stored in the first memory 131 is saved. In fact, as shown in Figs. 6a and 6d, the accompanying note set; At the same time, a write signal is applied to the memory 131 because of the on state of the switch 2c and the AND logics 131a. to 131d are put into the working state. When a key representing the first tone designation "G2" is pressed, the key operation signal generated by that key action is put on the line 10a with the note timing of "G". The output signal on line 10a is applied to memory 131 via AND logic 131a. At the same time, the note code which was put on lines 23a to 23e is applied to memory 131.

At this point in time, the signal on line 10a is generated from the OR logic 1405 with a time control, which matches the tone "G2". The

130014/1368

21 303660A

AND logic 1406 an output signal for the purpose of putting "1" in the bit position of the tone "G2" up to this Time did not exist. Since at this point in time the switches 2a and 2b are both in the off state. As shown in FIG. 5A, the increment signal H is found in the memory 131 as a write command created via the AND logic 1419 and the OR logic 1424. Saves on this write command the memory 131 the note code transmitted through the lines 23a to 231 is generated, and the block code that precedes. the AND logics 131a to 131d is output. Of the first memory 131 counts the number of times the code of "B" in the note code passed through the lines 23a to 231 is generated. The same thing happens

■] 5 for the second memory 132. The codes that are used during a Period of time entered in which all keys from C2 to B5 are scanned are in the Memories stored as those that are made to sound simultaneously. In this case, however, will only the code of "G2" is saved. If the keys "G3, B3" are then printed, these "G3, B3" stored as those that are to sound simultaneously, this being done during an operation that the resembles the above actuation. According to the set of accompanying notes, which is shown in Figs. 6A and 6D, "G3, B3", "B3", "G3, B3", "G3, B3", ... operated so that the accompaniment shown in Figs. 6A and 6D is stored in the memory 131.

The following explains the case where the accompanying data thus stored is read out, wherein only the rhythm diagram is considered, and in which the melody note set shown in Figs Figure 6D is shown; is played with the right hand.

In this case, the fetched 2C, which was previously in the on state according to FIG. 5 P, is switched to off and the switch 2a is switched to on. After setting this switch, the AND logics 161b to I61d

130014/1368 ORIGINAL BATHROOM

be switched to the working position. The AND logic I6ia however, in no case can it be switched to the working position by pressing the first group of buttons 1a will. Accordingly, the first group of keys is la is set to the key group for reading out the accompaniment stored in the memory 131.

First the first melody pitch is "G4" with the right hand entered. After pressing the "G4" key a key operation signal appears on the line 10c in the key input section 10 and becomes applied to the AND logic 25c by the AND logic 161C, which can be switched to the working position at this point in time. As an octave detection signal is applied from the block decoder 24 to the AND logic 25c via the line 24c, provided that the line 24c is selected, so to speak, the content of the block counter becomes "2", the actuation signal from "G4" is transferred to the Shift register 27 loaded by AND logic 25c and OR logic 26. Then it will be in the Shift register 27 shifted. A signal input to the shift register 27 is input to the buffer 28 read in when the output signal is generated from the AND logic 28a, i.e. when all the keys in the key input section 10 are completely scanned. According to the data read into the buffer 28 the tone generating circuit 29 forms a tone of the pitch "G4" which is then output by the speaker 4 is made to sound.

When the second melody tone "B4" is entered, will a musical tone corresponding to "B4" through the toner— generating circuit 29 formed via an actuation, which is similar to the foregoing and made to sound similarly.

Then press a key with "D5" with your right hand to enter the next melody tone "D5"

130014/1368

is pressed with one of the keys in the first key group 1a being pressed with the left hand. As a result of the keystroke actions, the tone "D5" sounds as in the previous case, which is entered with the right hand became. Pressing a certain key from the first key group 1a results in a key operation input signal that appears on line 10a. As a result, the OR logic 1405 generates an output signal with every temporal division of every tone

TO "C2 to B2", which in turn enters the shift register 1409 is loaded via the AND logic 1406. The AND logic 1421 is switched to the working position under the condition if the output from the AND logic 1406 is generated, the content of the counter 1402 is "0", and the switch 2a is turned on. After this Switching the AND logic 1421 into the working state, the address increment signal H is sent to the first memory 131 transferred. The contents of the shift register 1409 is transmitted in parallel to the latch circuit 1412. Since the data latched in the latch circuit 1409 is any one of the tones "C2 to B2" are, an output signal is generated by the OR logic 1412 and switches AND logics 131e to 131h the AND logic 1414 in the working position, which in turn is switched to the working position when the switch 2a is on. The contents of the shift register 1409 is fed in by the AND logic 1407 as long as the same key is pressed. Included the signal is continuously stored in the same place. As long as the key is pressed, generated accordingly, the AND logic 1414 continuously picks up the musical tone corresponding to the depressed key.

The first memory 131 is responsive to the increment signal H, which has been folded by the OR logic 1424 thereon to the note code on lines 23a to 231 of the touch decoder 23 with the previously stored score code comparator. ¹ \> If both note codes are

130014/1368

coincide with each other in time, becomes a "1" signal generated on the lines formed by the block code. In the present case it is first stored pitch "G2". Accordingly, when the note code of "G" is output on lines 23a to 231 is, the first memory 131 generates an output signal, which in turn is sent to the AND logic 25a is applied via the AND logic 31h. Therefore, two tones "G2" and "D5" become simultaneously in the musical toner diffraction circuit 29 formed and made to sound by the loudspeaker 4.

Thereafter, the melody in the melody note set shown in Figs. 6k and 6D is inputted with the right hand while any of the keys of the first key group 1a is pressed with the left hand to generate the rhythmic diagram as shown in the rhythmic note set in Fig Figures 6C and 6F are shown. As a result, the musical tone generating circuit 29 forms the musical tones with the pitches as described above in the musical score of FIG. 4 to make them sound through the loudspeaker 4.

In the above embodiment, the switch 2c is switched to on in the write position and switch 2a is switched to on in the play position for reading and writing the accompaniment. On the other hand, the switch 2d is in the write position is turned on and the switch 2b is turned on for reading and writing the melody and the second key group 1b is used as a key group for reading. In this case the Accompaniment shown in Fig. 6A and Fig. 6D played in that the first group of keys la with the left Hand operated. Any one of the keys of the second key group 1b is corresponding with the right hand actuates the rhythm diagram shown in FIGS. 6B and 6E, whereby the contents of the second memory

1300H / 1368

is read out.

In the first embodiment, the first group includes keys one octave, while the second group of keys is three octaves. The keypad 1 can be in a appropriate ratio of octaves to be shared and is not limited to the ratio of the above embodiment limited.

As explained above, in the electronic Organ of the embodiment either initially the accompaniment or melody can be saved. In the reading position, any one of the keys becomes a of the key groups, which by the functional division of the key field 1 with a given octave ratio were obtained according to the rhythm diagram the accompaniment or the melody. Therefore, even the beginner can make a difficult piece of music play in a simple manner as described in the music notation.

The electronic organ according to the second embodiment of the invention will be described below. The external view of the electronic organ of the second embodiment is essentially the same as that of FIG. 1, except that switch 2d is not used. The keypad 1 of the second embodiment is also divided into key groups 1a and 1b. The switches 2a to 2c are used to determine that the keypad 1 in the normal state, in the functional divided state is used, or that the played music data is either in the first or the second memory can be written, which is explained below.

The circuit arrangement of the second embodiment comprises the circuits shown in FIGS. 3A and 3C in the arrangement shown in FIG. The structure

1300 U / 136 8

The second embodiment also has five blocks and circuits to connect these blocks. The five blocks represent an input section 10, one Musical tone display section 20, a storage section 230 including first and second memories and their peripheral circuits, one Control section 240 for transmitting the control signal to the storage section 130 and the like and an amplifier 50 represent.

The key operation signal output from the input section 10 through the lines 10a to 10d is applied to the AND logics 261 a to 261 d, their output signals to the AND logics 25 a to 25 d be created. The key actuation signal, which is emitted through the lines 10a to 10d, is on a storage section 230 is applied. The signals fed into the memory section 230 are by AND logics 231a to 231d to the first memory 231 and applied to the second memory 232 by the AND logics 232a to 232d. The musical note code, delivered to the lines 23a to 231 is applied to the first and second memories 231 and 232.

The data read out from the first and second memories are determined by the AND logics 231e to 231h and the AND logics 232e to 232h are issued. From these signals from the logics the corresponding applied to the AND logics 25a to 25d. The AND logics 231a to 231d, 232a to 232d, 231e to 231h and 232e to 232h are switch controlled by the control signals B, C, E and D output from the control section 240 will. Furthermore, the control section 240 generates read /

Write control signals B and C for the first and second memories 231 and 232 and increment signals 3 and F for incrementing addresses of the associated Memories 231 and 232 in read and write mode.

When the control section 240 with the output signals from the switches 2a to 2c, with the output signals transmitted through the lines 10a to 10d of the input section 10 arrive, and the clock signal <f) A is applied is, it generates the control signal A for the AND logics 261a to 261d in addition to the control signals B through C for memory section 230. Details of control section 240 are in FIG shown. It should be noted that the input and

] 5 Output terminals of the circuit shown in Fig. 8 not in position with those of Fig. 3C circuit shown coincide.

The control section 240 has counters 2401 and 2402, the structure of which is that of the note counter 21 and the block counter, respectively 22 resembles. The counting cycle pA is applied to the first stage of the counter 2401. A signal that recognizes that the content of the counter 2401 has reached "12" is sent to the reset terminal of the counter 2401 created. The reset signal applied to the counter 2401 is sent to the counter 2402 as a count clock signal created. The output signal of the counter 2402 is input to a decoder 2403, the structure of which is similar to that of the Block decoder 24 is the same. The key press signals arriving through line 24a through 24d are is selected by a key timing detection circuit 2404 on the output from the decoder 2403 and the selected signal is output through OR logic 2405. Accordingly belong to the output signal from the OR logic 2405 bit time intervals that match all keys. That from the Or logic 2405 key actuation signal issued belongs to the key logics 2406 and 2407,

130014/1368

their output signals through an OR logic 2408 to a shift register 2409 with a 48-bit capacity be created. The output signal from the shift register 2409 is applied directly to AND logic 2407 and through an inverter 2410 to AND logic 2406. The AND logic 2406 generates an output signal, when it receives an additional key press signal. The AND logic 2407 generates an output signal, when it receives the same key press signal.

The parallel outputs from shift registers 2409 become a latch circuit 2412 transmitted when an AND logic 2411 recognizes that the content of counter 2401 is "12",

] 5 and the content of the counter 2402 is "3", so to speak all keys have been fully scanned. In conjunction with the output of latch circuit 2412, the lower twelve bits, i.e. the output signals from the bit positions of the latch circuit 2412 for storing the Key operation signal appearing on line 10a from interlock circuit 2412 by an OR logic 2413 and an AND logic 2414 issued as output signals in the form of a control signal E for the AND logics 231e to 231h. the remaining bit signals are output from the latch circuit 2412 by an OR logic 2415 and an AND logic 2416 in the form of a control signal D issued for the AND logics 232e to 232h.

The AND logic 2406 generates a "1" signal when another key is pressed. The output signal from the AND logic 2406 is applied together with the output signal (control signal A) from the inverter 2417, which is an inversion of the output signal from the switch 2a to the AND logic 2418th The output signal from the AND logic 2406 and the output signal from the OR logic 2421 for recognizing whether the content

1300U / 13B8 BAD ORIGINAL

of the counter 24C2 is "1 to 3" are applied to an AND logic 2419 together with the output from the switch 2a. The output signal from the AND logic 2406, the output signal which is generated "when the counter 2402 generates a" 0 "signal, and the output signal from the switch 2a are applied to an AND logic 2420. The output signals from the and- Logics 2418 and 2419 are applied to an OR logic 2422, which in turn generates an output signal as incremental signal F for the second memory 232. The output signals from the AND logics 2418 and 2420 are sent to the first memory 131 in FIG Form of the tone signal G applied.

The output signal from the switch 2b is generated for the memory section 130 as a control signal for the AND logics 231a to 231d and as a read / write signal for the first memory 131, ¹ W? denoted as P. The output ⁰ signal from switch 2c is generated as a control signal for the AND logics 232a to 232b and as a read / write signal for the second memory 232, where it is designated as D.

The following explains the case in which, with such a structure, the accompanying note set shown in FIGS. 6k and 6D is stored in the first memory 231, and the melody note set shown in FIGS. 6A and 6D is stored in the second memory 232 and when playing a piece of music, any one of the first key group la is used for an accompaniment game, when any one of the second key group 1b is used for a melody game.

To store the set of melody notes shown in FIGS. 6A and 6Ό, switches 2a and 2b are set to off, while switch 2c is set to on. Thereby, the pitch codes are loaded into the second memory 232 when the keypad 1 is operated

1300U / 1368 BAD ORIGINAL

will. Because of the on state of switch 2c, the second memory 232 is at this point in time in the ready-to-write position. If a key that the first tone "G4" is operated to store the "G4" data, it is operated by this key operation generated key actuation signal is given on the line 10c with the time interval "G". That Output signal in the line 1 "Oc is applied to the second memory 132 via the AND logic 232c, which was previously was switched to the working position by turning on the switch 2c. The signal on the line 10c is generated at this point in time from the OR logic 2405 with a time interval that leads to a Pitch "G4" matches. The AND logic 2406 produces an output signal. Since at that time the switch 2a is is in the off state, the output signal from the AND logic 2406 is the incremental signal F in the second memory 232 via the AND logic 2418 and the Or logic 2422 a. In response to this incremental signal F, the second memory 232 stores the note code this point in time and the block code output by the AND logics 232a to 232d. The second Memory 232 counts the number of output signals of the Codes of "B" in the note code carried by lines 23a until 231 is delivered. The same thing happens with the first memory 231. The codes that occur during a period of time are input by scanning all of the keys C2 to B5 are stored in the memory as well as those that are made to sound simultaneously. In this case, however, only the Code of "G4" saved. Accordingly, when a key "B4" is then operated, the "B4" data becomes stored during an operation similar to the previous one. Corresponding to that in FIGS. 6A and 6D The melody note set shown, the keys "D5", "B4", "D5", "E5", ... are operated one after the other so that the melody shown in Figs. 6A and 6D is stored in the memory 131.

To save the accompanying note ^{r;. 1} tzes the switches 2a and 2c, as shown in Fig. B * B -le shows, are set to off, while the switch 2b is set to Sin. With such a switching arrangement, the keypad 1 is actuated for storage. The first memory 231 is in the memory ready state at this time since the switch 2b is set to on. When a key representing the first tone "G2" is pressed, the key operation signal generated by this key operation is put on the line 10a with a note time interval of the tone "G". The output signal on line 10a is applied to memory 231 via AND logic 231a. The note code which was delivered on the lines 23a to 231 is applied to the memory 231 at the same time. At this point in time, the signal on line 10a is generated by the OR logic 2405 with a time interval that matches the tone "G2". The AND logic 2406 produces an output signal.

There. at this point the switch 2a is in the "off" position is, the increment signal is sent as a read command into the memory 231 via the AND logic 2418 and the OR logic 2423 given. In response to the read command, the memory 231 stores the note code, the is output through the line 23a to 231, and the block code output by the AND logics 231a to 231d will. Subsequently, when the keys of the tones "G3, B3" are printed, the data becomes this Tones "G3, B3" are stored as those that are to be sounded simultaneously with an operation being performed, which is similar to the previous one. Regarding the accompanying note set shown in Figs. 6A and 6D, the tone keys "G3, B3", "D3", "G3, B3", "G3, B3 ", ... are operated one after another so that the accompaniment shown in FIGS. 6A and 6D is stored in the memory 231 will.

The following explains the case where the

130014/1368 ORIGINAL BATHROOM

art stored melody and accompaniment read out considering only the rhythm diagram is, and the melody by pressing one of the keys in the second group of keys 1b by a single Finger of the right hand is played while the accompaniment is pressed by pressing one of the keys of the first Key group 1a by the piece of music previously stored in the first and second memories 231 and 232 is played. In this case, the switch 2a

] 0 is set to on, while switches 2b and 2c, like shown in Fig. 9C can be set to Off. After setting this switch, there are the AND logics 261a to 261d no longer in the working position. The first Key group 1a and the second key group 1b become.

^ 5 are set to the key groups to those in the first and second memory 231 and 232 to read out stored accompaniment and melody.

To play the piece of music, the first two notes of the melody of the musical score set shown in Figs. 6A and 6D are not accompanied by the accompaniment. Accordingly, one of the keys of the second key group 1b is pressed with the right hand. As a result of the key operation, an output signal appears on one of the lines 10b to 10d of the key input area 10. This output signal is not passed through the AND logics 261a to 261d and generates the increment signal F for the second memory 232 by the AND logics 2406 and 2419 and the OR logic 2422. In response to this inputted signal, the second memory 232 compares the note code which was output on the lines 23a to 231 of the note decoder 23 with the note code "G" which was previously stored. If these correspond to one another, the memory 232 generates an output signal and applies this to the AND logic 225e via the AND logic 232f in accordance with the previously stored block code (in the present case "G4" is stored

130014/1368

and therefore this belongs to the third octave).

The output signal of the AND logic <2406 is loaded into the shift register 2409 via the or logic 2408. The contents of the shift register 2409 are transferred to the lock circuit 2412 in parallel. The euf data transmitted to the interlock circuit 2412 corresponds to one of the keys of the second key group 1b. For this purpose, the OR logic generates 2415

IQ "1" signal, which in turn is indicated by the AND logic 2416 the AND logics 232e to 232h are created, whereby these are switched to the working position. The content of the shift register 2409 is given as long as the AND logic 2407, as long as the same key is pressed is. The signal is continuously saved at the same point. The AND logic 2416 continuously outputs an output, so long the button is pressed.

An octave detection signal is generated by the block decoder 24 applied to AND logic 25c through line 24c. When the line 24c is selected, i.e. when the content of the block counter 22 becomes "2", the operating signal of the tone "G4" is transferred to the shift register 27 the OR logic 26 inscribed. It is then inserted into the shift register 27. An input signal, which is input to the shift register 27 when the output from the AND logic 28a is generated, i.e., when all the keys in the key input section 10 are completely scanned is written into the buffer 28. According to the data stored in the buffer 28 the tone generating circuit 29 forms a tone "G4", which is then transmitted through the loudspeaker 4 to Tones is brought.

To sound the second note of the melody, one of the keys in the second group of keys 1b is pressed so that

1300U / 1368 BAD ORiGSNAL

] by an operation similar to the previous one the tone generation circuit 29 generates a musical tone forms with a pitch corresponding to the tone "B4".

To generate the next melody note, any one of the keys of the second group of keys 1b is pressed by the right hand, and one of the keys of the first group of keys 1a is pressed by the left hand. As a result of the key depression, as in the above case, a sound is generated which is due to the key operation output by the second key group 1b. Pressing the specific key from the first group of keys la results in a key operation output signal appearing on the line 10a. The output signal generates the incremental signal G for the command of the read operation for the first memory 231 through the OR logic 2405, the AND logics 2406 and 2420 and the OR logic 2423. After receiving the signal G, the first memory 231 compares the note code, which was delivered to the lines 23a to 231 of the note decoder 23, with the note code which was previously stored. If these coincide with one another, the memory 231 generates a "1" signal corresponding to the previously stored block code, which in turn is applied to the AND logics 231e to 231h. In the present case the pitch is first stored in "G2". Therefore, when the note code "G" is generated on lines ?? a through 2, the memory 231 generates an output signal. The output signal generated by the memory 231 is applied to the AND logic 25a via the AND logic 231h. An operation similar to that in the reading manner of the second memory 232 is performed.

The key operation output on line 10a loaded into shift register 2409 and on the interlock circuit 2412 has been transmitted,

1300 14/136 8

is determined by the OR logic 2413 and the AND logic 2414 applied to the AND logics 231e to 231h. As a result an operation similar to that in reading from the second memory 232 is obtained.

Therefore, the musical tone generating circuit 29 simultaneously generates two tones, "G2", from the first memory 231 is read out, and "D5" which is read out from the second memory 232. These tones will be then made to sound by the loudspeaker 4.

Then, any one of the keys of the second key group 1b is pressed with the right hand corresponding to the Rhythm described in the rhythm diagram shown in Figs. 6B and 6E. In a similar way One of the keys of the first key group 1a with the left hand becomes one of the keys according to the rhythm described in the rhythm diagram shown in Figs. 6C and 6F. As a result the musical tone generating circuit 29 forms musical tones having pitches as shown in FIGS. 6A and 6 Fig. 6B are described musical score set, which is then sounded through the loudspeaker to be brought.

In the embodiment described above is one octave is assigned to the first group of keys, while three octaves are assigned to the second group of keys. The keypad 1 can be divided by a corresponding ratio of octaves and is not open the aforementioned embodiment is limited.

As described above, the electronic organ of the second embodiment stores both the Accompaniment and melody data. When reading, one of the keys in each key group identified by the functional parts of the keypad 1 is obtained with a predetermined octave ratio, accordingly

transferred from the AND logic 3430 to the first memory 331, so that the AND logics 331 a to 331 d are placed in a certain sound state. In this sound state, a key of the first note β "G2" is pressed. After pressing a key actuation signal is given on the line 10a with the note time interval "G". The output signal from the line 10a is applied by the AND logic 331a to the first memory 331, while simultaneously

] q a note code output on lines 23a to 231 is applied to the first memory 331. That given at this point in the line 10a Signal is output from the OR logic 3405 at a time interval that matches the note "G2", so the AND logic 3406 generates a "1" signal because "1" up to this point in the bit position of the Grade "G2" was not available.

Accordingly, the AND logic 3432 is in the full sound state in order to generate an output signal and an increment signal G is applied as a write command by the OR logic 3436 to the first memory. As a result, the note code given on the lines 23a to 231 and the block code given by the AND logics are written in the first memory 331. The first memory 331 counts the number of output signals of the code "B" of the note codes given on the lines 23a to 231 and stores the code input during a unit of time during which all the buttons from C2 to B5 were scanned to make them sound simultaneously. Only the code "G2" is saved in it. Subsequently, when the keys of notes "G3, B3" are pressed, these notes "G3, B3" are stored as those to be sounded simultaneously, and an action similar to the above is performed. According to the in Fig. 6A and 6D

1300H / 1368 BATHROOM ORIGINAL

"G3, B3", "D3", "G3, B3", "G3, B3", ... are successively operated so that the accompaniment shown in FIGS. 6A and CD is stored in the memory 331.

The following will explain the case where the accompaniment thus stored is read out, considering only the rhythm chart, and the melody shown in Figs. 6A and 6D is played with the right hand. In this case, as shown in Fig. 12C, the switch 2A is brought to the reading position while the switch 2b remains unchanged. Due to the setting of the keys and the above-mentioned key field separation definition as the key time interval of the first key group 1a, the output signal at the reset terminal "Q of the RS i-'lip-flop circuit 3417" is "1" while at the key time intervals C3 to B5 the output signal at the setting output Q " Accordingly, when the first melody note "G4" is played with the right hand first, the key operation signal appears on the line 10c of the key input section 10. At this time, the output of the set terminal Q of the flip-flop circuit 3417 becomes "1" The AND logic 3426 is accordingly in the fully switched state, so that an enable signal A from the OR logic 3439 is applied to the AND logics 361a to 361d Logic 361c. An octave detection signal from the block decoder 24 is applied to this AND logic through the line 24c line 24c is selected for this purpose, the content of block counter 22 is "22". The key operation signal “G4” is loaded into the shift register 27 by the AND logic 25c and the OR logic 26. It is then shifted into the shift register one after the other.

1300U / 1368

If, accordingly, the AND logic ° 3a eir, Ausvicjss igi: <~ 1 generates, that is, when all keys of the key input area 10 have been scanned, the signal input into the shift register 27 is loaded into the buffer. The musical tone generator circuit 29 generates a musical tone having a pitch "Q4" in accordance with the data loaded in the buffer 28 and makes it sound through the speaker 4.

] 0 When the second melody note "34" is played, the musical tone generating circuit 29 generates a musical tone having a pitch corresponding to the note "BA ", again performing an operation already described above.

When the melody note "D5" is played thereafter, the key of the note "D5" is pressed with the right hand while one of the keys of the first key group 1a is operated with the left hand. Accordingly, the sounding of "D5" occurs as in the previous case. However Venn a predetermined key of the first key group is operated 1a, is the AND logic 3432 in the fully connected state, since the RS flip-flop is at this time 341 7 in the reset state, with the result that RS Fiip- Flop circuit 2425 is brought into the set state and its output generates an enable signal E through an AND logic 3434 to the AND logics 331 e to 3 31h.

At the same time, the AND logic 3432 is switched to the working position to generate an incremental signal G in the first memory 331 to transfer. After receiving the increment signal G, the first memory 331 compares a note code delivered to the line 23a to 231 of the note decoder 23 with a previously stored one Note code, and, if a coincidence between these is detected, generates an output signal in the line what is saved by the above

Block code has been defined. In this example, the first stored pitch is "G2". Accordingly, when the note code of "G" is put into the line 23a to 231, the first memory 331 generates an output signal, which in turn is applied to an AND logic 25a. Accordingly, the musical tone generating circuit 29 simultaneously forms two tones "G2" and "D5" and makes them sound through the speaker 4. If the key operation is then stopped by the left hand, the AND logic 3409 generates a "1" signal. At this time, since the signal at the reset terminal Q of the RS flip-flop circuit 3417 is "1", a reset signal is sent to the RS flip-flop circuit 3435 through the AND logic 3432. Accordingly, the signal at the set terminal Q becomes "0" and the switching control signal for the AND logics 331e to 331h becomes "0", whereby the sounding of the Murik note "G2" stops.

Then the melody in the melody sheet 2 shown in Fig. 6A and Fig. 6d with the right Hand played while one of the keys of the first key group 1a with the left hand corresponding to the Rhythm diagram is operated on the rhythm note set shown in FIGS. 6C and 6E. The musical tone generation scarf circle 29 generates musical tones with pitches as described in the notation, and makes them sound through the loudspeaker 4.

In the above-mentioned embodiment, the Switch 2b set to the first contact for reading and writing the accompaniment. On the other hand, can the reading and writing of the melody take place in that the switch 2b-is set to the second contact will. In this case, the left hand plays the accompaniment, with the functionally divided key group is used, i.e. the group of keys from a key with the pitch C2 to a key with the pitch

is determined by the separation. The right hand in turn actuates the second group of keys Ib, which is used for Reading and playing the melody with the accompaniment shown in Fig. 6b and Fig. 6E is divided. Even though in this case the actuation circuitry differs from that of the previous case, it is the same Circuit operation is essentially that mentioned above, so reference is made to it.

While in the above case the pitch arrangement of the keypad 1 is set to the key with the pitch C3, it can of course be as described above also be at any other pitch.

As described above, the electronic organ according to the third embodiment stores either the accompaniment or the melody. When reading, a of the keys in the key group that is functionally divided according to the rhythm diagram of Accompaniment and the melody. Accordingly, even a difficult piece of music can be used by the beginner can be played in a simple manner. Since the functional division of the keypad on any pitch or Key position can be set, the range of pitches, manual playing, as well as the Read allows to be set accordingly.

The electronic organ according to the fourth embodiment the invention is described below. The external view of the fourth embodiment of the electronic The organ is essentially the same as that of Fig. 1. In the present embodiment switches 2b to 2d are not used. The switch 2a is a five-contact type.

The circuit arrangement of the fourth embodiment consists of the circuits shown in FIGS. 3A and 3E with the arrangement shown in FIG. The structure and operation of the circuit shown in Fig. 3Λ has already been described in the first embodiment, to which reference is made. The present embodiment also has five Blocks and circuitry to interconnect these blocks. These five blocks are a key input section 10, a musical tone generation section 20, a storage section 430 including a first memory and a second memory 432 and their peripheral circuits, a control section 440 for transmission of the control signals to the storage section 430 and the like and an amplifier 50.

The And Logilcen 431a to 431d and 432a to 432d are provided with control signals B and C are applied, which are output from the control circuit 440 described below. Furthermore, the control circuit 440 generates control signals B and C as write / read signals to the first and second memories 431 and 432. The reason why the

] q memories 431 and 432 are provided in the memory section 430 is the one that the accompaniment and melody in the first or second memory by the Key actuation of the key input area 10 must be stored by a player. These two Memories can be stored in a single memory using additional simple circuitry be united.

The first and second memories 431 and 432 are generated with the signals G and F from the control circuit 440 applied to increment the content of a address-setting circuit, which is provided in the memory, and used to determine the writing or reading.

A twelve-bit signal carried by lines 23a to 231 is output from a note decoder 23 is entered as a note identification signal in the memories 431 and 432 entered. A note code issued on lines 23a to 231 and a block code issued by the AND logics 431a to 431d or 432a to 432d are issued are written into the memories 431 and 432.

The control section 440 is shown in detail in FIG. IQ As an aside, it should be mentioned that the input and output connections of the circuit shown in Fig. 14 are not in position with those of that shown in Fig. 3E Circuit match.

According to FIG. 14, the 2: counters 4401 and 4402 operate synchronously with the note counter 21 and with the pin counter 22, respectively, which are shown in FIG. 3A. The counting clock P ^, which is similar to that applied to the note counter 21, is applied to the first stage of the counter 4401. The counter 4401 is reset by a signal which is put on a line 4403 when the content of the counter 4401 reaches "12". The reset signal, which was put on a line 4403, is applied to the counter 4402 as a counting signal. The output of the counter 4402 is applied to a key press detection circuit 4404. The key operation signals which come through the lines 10a to 10d of the key input section 10 are separated into octaves by the AND logics 25a to 25d, the separated signal being output by an OR logic 4405. The key operation signal which is output from the OR logic 4405 is applied directly to the AND logics 4406 and 4407 and through an inverter 4408 to the AND logic 4409. The output signal from a shift register 4410 with a capacity of 48 bits is applied through an inverter 4411 to the AND logic 4406 and directly to the AND logics 4407 and 4409 «These AND logics 4406, 4407 and 4409 generate" 1 "-

The output signals from the AND logics 4406 and 4407 are applied to the shift register 4410 by an OR logic 4412. The output signal the AND logic 4406 becomes a division defining contact together with the output signal of switch 2a is applied to an AND logic 4413. That Output signal from AND logic 4413 is used as a write

■) 5 Form of a note code and a block code, where the Contents of the counters 4401 and 4402 are retrieved, which are synchronized with the note counter 21 and the block counter work. The output signals from these memories are sent to a coincidence circuit together with the output signals from the counters 4401 and 4402

4416 created. The coincidence circuit 4416 compares the data output from the counters 4401 and 4402 with the code output from the memory 4414 or 4415. When these are coincident with each other, the circuit 4416 applies the coincidence signal to the set terminal S of an RS flip-flop circuit 4417. An output signal is applied to the reset terminal K of the RS flip-flop circuit 4417, which is obtained when the output signals appearing on the lines 4418 and 4403 when the content of the counter 4402 becomes "3", to the AND logic 4419 can be placed. The output signal at the set output Q of the R-ε flip-flop circuit

4417 is applied to the AND logic 4420 and 4421, to which the output signals from the AND logics continue 4406 and 4409 are applied. The output signals the AND logics 4420 and 4421 become an R-S at the set connection S and at the reset connection R

The output signal at the reset to the CJ of the R-S flip-flop circuit 4417 is applied to the AND logics 4423 and 4424, ar. the the output signals from the AND logics 4406 and 4409 continue to be created. The output signals off the AND logics 4423 and 4424 are connected to the set terminal S or the reset terminal R of an R-S flip-flop circuit 4425 created.

ΙΟ The output signal at the set terminal Q of the R-S flip-flop circuit 4417 is fed to AND logic 4426 and the output at reset terminal Q is fed to the AND logic 4427 applied. The AND logics 4426 and 4427 continue to operate with an output signal of the contact of the switch 2a for determining the reading from the first and second memories 431 and 432 and applied to the outlet signal from the AND logic 4406. The AND logics 4426 and 4427 are combined with the OR logics 4428 or 4429 connected.

The OR logic 4428 continues to use the output signal from a contact of the switch 2a to determine of writing in the second memory 432 and applied to the output signal from the AND logic 4406. The OR logic 4429 is with the output signal from the contact to determine the writing into the first memory 431 and with the output signal acted upon from the AND logic 4406. The output signals from the OR logics 4428 and 4429 are applied as incremental signals F and G to the second and first memories 432 and 431, respectively.

The following explains the case in which, of four octaves of the touch panel, the octave with the lowest pitch, that is, one group before. Button. C2 to B5 (hereinafter referred to as the first key group 1a) are used for the accompaniment reading game and the keys B2 to B5 (hereinafter referred to as the second key group 1b) are used for the melody reading game. For this purpose, the contents of the first and second memories 431 and 432 are read out.

First, to determine the selection or division position on the keypad, the switch 2a, as shown in Fig. 15, is in the V / ahl- or division contact

Position brought and ar.sch] eating a test of "C3" is pressed. Through the pusher - the door forward. A key operation sign appears on the door. C 10b of the key input area 10 with the time interval of "C". The key operation signal is applied to the key depression detection circuit 4404 of the control section 440. The key depression detection circuit 4404 produces a "1" signal at a specified one Line of logic 405 according to the contents of the counter

] 0 4402. As a result, the Urd logic 4406 generates a "i" signal, just like the ünd logic 4413 generates a "1" signal, so that the contents of the counters 4401 and 440? ir the memories 4414 and 4415 is loaded. Accordingly, the coincidence circuit 441b generates, if necessary, a coincidence signal with the time interval before C3 during the sampling, whereby the RS flip-flop circuit 4417 is set. The case will now be explained in which the accompanying note set shown in FIGS. 6Λ and 6D is in the first memory 431 inid of the ir.

Figures 6A and 6D in the second helodic note set Memory 432 is stored.

In order to store the musical note set shown in FIGS. 6A and 6Ό in the second memory 432, the switch 2a is set to the position to determine the writing in the second memory, and the pitches are shortly thereafter in the second memory 422 by actuating the keypad 1 written.

O ₀ At this point in time, the second memory 432 is in the ready-to-write state after receiving an enable signal for the AND memories 432a to 432d. To save the first note "G4", press the key forward. "G4" actuated to give a key actuation signal

or the line 10c at a time interval of "G" zv , which is a note time interval which is in turn applied to the second memory 432 via the AND logic 432c. to

BATH ORIGINAL

At this point in time, the signal given on the line iOc is output by the OR logic 4405 with the time interval that matches "G4". Furthermore, the AND logic 4406 generates a "1" output signal for the purpose that "1" is not present in the bit position of "G4" in the shift register 4010 by then. The AND logic 4430 is therefore completely switched to the working position in order to generate an increment signal F as a write command signal for the second memory 432 via the OR logic. As a result, the second memory 432 stores note codes output from the lines 23a to 231 and a block code output from the AND logics 432a to 432d. The second memory 432 counts the number of outputs of the code of "B" of the note codes put on the lines 23a to 231. The same is the case with the first memory 431. Codes entered during a period in which all of the keys C2 to B5 were scanned are stored in the memory as those to be sounded simultaneously. In this case, however, only the code of "G4" is saved. Accordingly, when a key of "G4" is subsequently operated, "B4" is stored by an operation similar to the above. Corresponding to the melody note set shown in FIGS. 6A and 6Ώ, "D5", "B4", "D5", "E5" ... are pressed one after the other, so that the melody shown in FIGS . 6A and 6Ώ is stored in the second memory 432 . In order to store the set of accompanying notes, the switch 2a is brought into the position shown in FIG. 15C in order to determine the writing in the first memory 431. The keypad 1 is then operated in order to store the pitch codes in the first memory 431. At this point in time, the first memory 431 is in the ready-to-write position as a result of receiving a release signal for the AND logics 431a to 43Id. When the key of the first tone "G2" is pressed

1300 rev / 1368

the key actuation signal is given on the line 10a as the note time interval of "G". The output signal from the line 10a is applied to the first memory 431 by the AND logic 431a. At the same time, the note codes which have been output on the lines 23a to 231 are applied to the first memory 431. At this point in time, the signal given to line 10a is received by the OR logic 4405 at a time interval that matches "G2". The AND logic 4406 generates a "1" output signal, since "1" was not in the bit position of "GP" in the shift register 4410 until then. Accordingly, the AND logic 4431 is in its fully switched operating state "to generate an increment signal Π? .Ls write signal for the first memory 431 via the OR logic 442 9. As a result, the first memory 431 stores the note codes which are based on the Lines 2? A to 2? 1 were given, and a block code which proceeded from the AND logics 3ia to 31d. Subsequently, when the keys of the notes "G3, B3" are operated, these notes "G3, B3" become those to be sounded simultaneously, performing an operation similar to the above. According to the accompanying note set shown in Figs. 6A and 6D, "G3 _f D3", "D3", "G3, B3", " G3 _f B3 ", ··· so that the accompaniment shown in Figs. 6A and 6D is stored in the first memory 431.

The following explains the case where the stored in the first and second memories Melody and accompaniment are read out and played, considering only the rhythmic diagram, in such a way that any of the keys in the second group of buttons 1b is operated with a single finger of the right hand for the melody and then one of the keys in the first key group la

5-0 3036804

a single finger of the left hand is pressed for accompaniment. In this case the switch 2a is on a position defining reading for the first, and second memories 431 and 432 are set as shown in FIG 15D is shown. After the switch has been set, the AND logics 46ia to 46id are no longer in the working position switched and the first and second group la and 1b are on those keys for the accompaniment and the melody set in the first or two-

} q th memory 431 or 432 are stored. Since the keypad 1 is divided thereby, the ES flip-flop circuit 4417 has "1" at the reset terminal "q " at the key time intervals from C2 to B2 and at the set terminal Q "1" at the key time intervals C3 to B5.

When playing the piece of music shown in Figs. 6A and 6D the first two notes of the melody shown in the figures are not affected by the accompaniment accompanied. Accordingly, any one of the keys of the second group of keys ib by the right Hand operated. With this key operation, it will appear on lines 10b to 1 Od in the key input section 10 generated output signal on the key press detection circuit 4404 created without going through the AND logics 461b to 46id. So did at this point the set terminal Q of the R-S flip-flop circuit 4417 has the value "1". Therefore the logic state is the AND logic reaches 4420, leaving the R-S flip-flop 4422 is brought into the set state. Their output signal v / ird as control signal D by the AND logic 4432 placed on the AND logics 432e to 432a.

At the same time, the AND logic 4426 is more complete logical working situation, where an incremental signal F is output to the second memory 432 by the OR logic 44? 8. On this increment signal

1 300H / 1368

nal F, the second memory 432 compares the note code on lines 2 3a to 2 31 of the note decoder 23 with the previously saved note code. If these coincide with each other, will an output signal is generated which is sent to the previously stored Block code is issued. In the present embodiment, it is in the second memory 432 first stored pitch "G4". Hence it becomes an output generated, which is output via the line to the AND logic 25c.

Since an octave detection signal is applied from the block decoder 24 to the AND logic 25c via the Leitvmg 24c, if the line 24c is selected, that is, if the content of the block counter 22 is "2", the key actuation signal is fed from "G4" into the shift register 2 7 via the AND logic 25c and the OR logic 26 and shifted one after the other in the shift register. When the AND logic 28a produces an output, i.

when all the keys of the key input section 10 are completely scanned, the signal input to the shift register 27 is loaded into the buffer 28. The musical tone generation circuit 29 forms a musical tone with the pitch "G4" corresponding to the data fed into the buffer 28, and brings it with the help of the loudspeaker 4 for sounding.

When the key actuation with the right hand is stopped, the AND logic 4409 generates an "i" signal with this time interval. At the same time, a reset signal is sent to the R-S flip-flop 4422 Output via the AND logic 4421, since the R-S flip-flop circuit 4417 is in the set state. Accordingly the set terminal Q of the flip-flop circuit 4422 "0", whereby the generation of an enable signal for the AND logics 432e to 432h and the sounding of the musical tone "G4" are stopped.

1 300H / 1368

If one of the keys of the second key group 1b is then actuated to generate the second melody tone is, the musical tone generating circuit 29 forms a musical tone with a pitch corresponding to the key "B4" and this is done by an operation similar to that mentioned above.

To generate the melody note, the right hand presses any of the keys in the second group of keys 1b, while the left hand presses any of the keys in the key group la for the accompaniment game. Is the Phonetic formation attributed to the key actuation of the second key group 1b, it becomes as in the preceding Case carried out. If a certain key of the first key group la is operated, the AND logic is 4423 saturates since the R-S flip-flop 4417 is in the reset state at this time. Therefore, the E-S flip-flop circuit 4425 is set, with an output signal as an enable signal through the AND logic 4433 is generated to AND logic 431e to 431h will.

At the same point in time, the AND logic 442 7 is saturated, an increment signal G being output to the first store 431. After receiving the increment signal, the first memory 431 compares the note code which was delivered into the lines 23a to 231 of the note decoder 23 with the previously stored note code. If these coincide with each other, an output signal is generated on the line, which is determined by the predetermined block code. In this case, the pitch first stored in the first memory 431 is "G2". Therefore, when the note code of "G" on the lines 23a appear to 231, generates the first

^ 5 memory 431 an output signal, which in turn is sent to the AND logic 25a is applied. Produced accordingly

the musical tone generating circuit 29 simultaneously two tones "G2" and "D5" and brings them through the speaker 4 for sounding.

When the key operation is stopped by the left hand, a reset signal is given by the AND logic 4224 to the R-S flip-flop circuit 4225, since at this point the AND logic 4409 has a "1" signal and the reset terminal Q of the R-S flip-flop circuit 4417 is "1". Accordingly, the set terminal Q of the R-S flip-flop circuit becomes "0" and that Switching control signal E for the AND logics 431e to 431h becomes "0", which results in the end of the tone formation of the musical tone "G2".

Subsequently, the right hand operates any of the keys in the second group of keys 1b in accordance with the rhythm shown in FIGS. 6D and 6E, while the left hand operates any of the keys in the first group of keys la in accordance with the rhythm shown in that shown in FIG. 6G and Fig. 6F is described the rhythm diagram shown. As a result, the musical tone generating circuit 29 forms musical tones having pitches as described in the musical tone set of FIGS . 6k and 6D.

In the above embodiment, one octave is assigned to the first group of keys while three octaves are assigned to the second group of buttons. The keypad can be configured with an appropriate octave ratio be divided and is not limited to the above ratio.

As described above, the electronic stores see organ of the fourth embodiment of the invention beforehand both the melody and the accompaniment.
